Music on NAS with iTunes server. How to sync iPhone?
I keep my music collection on a synology NAS, which has a built-in iTunes server. I can see it fine on the mac that I use to sync my iPhone by selecting it in the pull-down in the upper left, but when I sync my iPhone none of the music shows up. My understanding is that home sharing won't work, because the music must be on the local machine to sync a device. I suppose that I could ignore the server and import all the music onto the mac (without copying), but that would mean that I need to "manually" update this particular mac any time music is added or deleted from the library - an error-prone hassle, unless there's some sort of auto-update that I don't know about
Is there a clean way to do this?
